Optimization of Coagulation and Flocculation Process in Wastewater Treatment of the Food Industry: A Laboratory Study
Background and Objectives: Food industry wastewater has a high pollution load, which is due to water consumption at various stages. In the absence of adequate wastewater management and supervision of the food industry, this wastewater can be considered as a source of environmental pollution. This study aimed to optimize the coagulation and flocculation process for the treatment of food industry...
متن کاملEvaluation of the Performance of Dual Polyelectrolyte Systems on the Re-Flocculation Ability of Calcium Carbonate Aggregates in Turbulent Environment
Flocculation can be used in turbulent environments resulting in floc breakage due to shearing. The degree of re-flocculation relates directly to product quality and process efficiency. This study aimed at looking for alternatives to improve the re-flocculation ability of aggregates when polyelectrolytes (PEL) are used as flocculation agents. Moreover, because branched PEL have proved previously...
متن کاملSelective Flocculation for Coal De Mineralization
Selective flocculation has long been suggested as a method for the treatment of ultra-fine particles typical of which are those produced in a de-sliming process ahead of flotation. In this paper the results of the coal de-mineralization, using synthetic polyacrylamide polymers, are presented. A prescreening test on the suitability of the polymers using Run-Of-Mine (R.O.M.) coal and artificial m...
متن کاملMethods for recovering poliovirus and rotavirus from oysters.
Polioviruses and rotaviruses are potential indicators of sewage pollution of water and shellfish. Several methods for detecting these viruses in oysters were assessed. Elution-precipitation involving Catfloc for clarification and skim milk for subsequent flocculation resulted in the recovery of an average of 79% of poliovirus type 1 and 37% of rotavirus SA-11 from oyster homogenates inoculated ...
متن کاملImproved method for virological analysis of food.
A single, simple method for recovering enteroviruses from several different kinds of food, such as ground beef, fish, oysters, and mussels, has been improved. First, sample contamination technique was studied. It appears that virus adsorption occurs at food pH and varies according to the kind of food and the food-virus exchange surface. Second, virus recovery was evaluated. According to the exp...
